NELSON TROYER, OF PORTLAND, OREGON.

CAN-READING MACHINE.

Be it known that NELSON Taovnn, a citizen 1 of the United States, residing at Portland, in

.the county of Multnomah and, State of Oregon, hasj'lnvented new and useful improvements n Can-Lieading Machines, of which the following is a specification.

, My invention relates to improvements in machines for heading cans.

it consists in the combination of parts whereby the heads may be applied to both ends of a can body simultaneously, and in end view of the same. F 5 is a side elevation of a mold open. Fig. 6 is a plan view of amold. Fig. 7 is aside elevation of one of the'duplicate supports for the molds. Fig. 8

is a side elevation of the sa'me showing one of t l'ie'moids in' place and open.

It is the object of my invention to provide means by which can bodies are delivered in a substantially horizontal position to molds carried by suitable duplicate supports, and

at the same time to deliver can heads to said molds so as to face opposite ends of the can. Suitable mechanism is provided whereby during the rotation of the duplicate supports,

I the molds are closed so 'as to aline the can heads with the can body, and the parts are subsequently moved to press the heads simultaneously upon the can body ends; the molds being afterwards opened, and the completed can delivered to a suitable discharge.

The machine is provii led with suitable duplicate supports for the molds, one of these supports being shown detached in Figs. 7 and 8. These supports are mounted upon the shaft F, and secured thereto by keys 19. These supports carry two opposed sets of molds, one at each end of the .position of the can body. As shown, there are four sets of molds carried by the duplicate supports and they are slidable thereon, being retained by guide plates'll)". The duplicate supports carry the'said sets of'molds equi-distunt around their periphery; said molds being ad apted, to receive can bodies and can heads which ard; delivered into the molds simultaa l l l l e Patented Nov. 19, 1907.

duplicate supports the molds are closed upon the can bodies and headsfand the portion carrying the heads is advanced so as to place the heads upon the ends of the can bodies. Motion may be transmitted to revolve this apparatus from any suitable motor, and the intermediate mechanism for transmission is here shown in the form of gears, one of which, H, is mounted upon the shaft F, and ower is transmitted to it from a pu ley. 1. p s many of the molds may he installed upon the duplicate supports as may be found desirable. l have found in practice that four of such molds operate very evenly and advantageously, but the number may be increased or diminished to suit the required capacity, and the operation is continuous and smooth.

Each mold consists of two parts 3-3*. In this description I will call the part 3 the outer half, and the part 3 the inner half. The outer half mold is hinged or fulcruined to a plate or support 16 above the inner half, and

admitting the can head and the end of the body. it will be understood that there will be two of these molds axially in line with each other and opened and closed in unison so that the ends of the can body are received into the molds and a can-head is delivered into each portion in line with the ends of the can body. The description of the operation of one of these molds applies to both.

The upward movement of the outer half 3 of the mold when opened by the action of l he spring 5 is limited by a stop (5, which consists of a scre\\"-threaded shank fitting into the plate 16 and having a disk or collar 6" formed upon it. The arm carrying the said outer hall 3 of the mold is perforated so that the stop passes through the opening, said opening being large enough to allow the arm to move freely, and the enlarged collar 6 upon the stop limits the motion of the outer half of the mold. 7 is a roller journaled upon the upper half 3 of the mold. 8, ligs. 1 and .2, is a cam so located that the roller 7 will travel in contact with the cam during a portion of the revolution of the apneously with and opposite the ends of the paratus. V When the roller 7 comes in concanbodies- During the revolution of the tact with the cam it is acted upon by the cam to close the mold. The revolution of by a set screw 4 which are formed by the castings A which roller 15.

the central part and the movement of the molds will be clock-wise when looking at the end view Fig. 1. This roller 7 is mounted upon an eccentric sleeve 9 which is turnable upon a bolt 10, and is locked in place by a nut 11 which screws upon the bolt and against the eccentric. By loosening the nut, the eccentric may be turned'so as .to move the roller out or in and thus adjust it forany errors in wear. A plate or su port 16 carrying theiouter half 3 of a mol has upon the end opposite the mold a hub. '13 through which passes a stud upon which is turnable a That ortion of the stud upon which the roller is turnable is eccentric to the part which passes throu h the hub, and the shaft is normally loc ed in place 12 which screws into the hub and the point binds against the shaft. By loosening this screw and a lock-nut12 the stud may be turned around and with it the eccentricportion carrying the roller 15 so that the latter may be advanced in either direction, and as this roller travels in a cam slot 14', to be hereafter described, it will be manifest that the outer half of the mold can be adjusted endwise by these movements. The inner half 3 of the mold iscarried upon a plate 17, the rear end of which has journaled upon it a roller 18 and this roller of each inner half molil enters a cam slot 14 which acts to retract ,the mold and release the can after the heads have been laced thereon as will be hereafter more fu lydescribed. The cams 14-14= are fixed with relation to the turnable portions of the machine, and are prevented from turning by screw-threaded studs 14' passing thro'ug l the pillow-blocks, as shown in Fig. 2, and held in place by lock-nuts 14. B means of these lock-nuts the studs, and with them the cams, may be moved in or out, to allow minute compensations for wear and var ing lengths of the cans as previously descri )ed.

The can bodies are delivered into a runway A which is formed in any suitable manner, and has an incline sullicient to allow the cans to roll down and pass from the runway into a substantially vertical channel or chute which carries-the cans down in such osition that they will be delivered to the mol s as the latter arrive opposite the lower end of the chute. Exterior to the runway which carries 5 heads. This sizing may be determined by'ad with the-shoulder the can bodies are channels or chutes B into which the can heads are placed standing vertically on edge, and maintained in this osition within the channels, the inner wal s of form the rumvays supporting the cans and on the outer sido'by plates, the two forming the channels or chutes B between which the can heads are supported. Both heads and cans reach the assembling ortion of the apparatus together and are relivered to the molds at the point C. The canhe'ads and bodies" arriving at the machine, the cams 8 and 14 having previously released the outer half molds 3, and allowed them to open, and also v retracted the part carrying the. outer half molds, the Inner half 3*" will thusbe exposed so that the can bodies and can heads may he.

delivered simultaneously into the molds. This. opening of the molds takes-place when they are ap roximately in 'a-T'vertical; line -7, 5 above the -axis of the machine, and before-the; cans and heads have been delivered intothei v molds. The cam slots 14thenacti1ponthe rollers 15, advancing the plate 16 and the outer half mold until the inner ends 0E th" molds are substantially in the same plane and the surface of the hub 13 hasbeenad. vanced into contact with the inner end of the} part 17 which carries the lower half mold 3}? as shown at X in Fig. 3. The rear faces of? 8,5,; the counterbores 3 of both outer and inner} halves will then be brou ht into the same; plane, during this time t e mold willilhave" traveled from about the vertical position to a point;about 45 in advance thereof.;, The rollers 7 of thezquter half molds now pass bea, neath the stationary cams 8, and thus act to, close the outer halves 3 of the molds down, upon the inner halves 3. This closin jof the molds rounds up and sizes the ends 0 the 9:5? caubody so that they may enter the cani justment of the eccentric 9 as reviously 'de scribed. The two parts of t e moldsal then by reason of the contact of the hub 13 0 formed by the end of the part 17, in condition to-be advanced in unison, and this is efl'ected'by the further movement of the machine and theaction of. the

cams 14 which force the can heads upon the L05 I ends of the bodv. At this oint the inner cam slots'14 will in practice e so constructed as to allow a proper clearance, and notinterfere with the action of the cam slots 14... The molds will now have reached a about 90 away from the verticalor in a iori f zontal line through the axis, and at this oint;

' the rollers 7 leave the cams 8: This a lows the springs 5 to press the outer half 3 of the" mold open, turning upon its pivot or fulcrum point 4 until the stop 6 arrests its further movement .as previously described.' From this point to a point about 180 and in a vertical line through the axis, the outer half of the mold is moved back to its outward posi- 12i) 7 tion by the action of the cams 14 upon the rollers 15. The 0 )posing molds are nowseparated sullhiently to release the can by the action of the inner cam grooves 14 upon the rollers 18 which se arate the opposing molds sulhciently to re ease the can which now has its head securely fastened u 11 its opposite ends. The can thus releaser is extracted from the molds by means of a curved iron or extractor 20, and as the outer orointyuof p of the same mold bein half of the mold wil be free to be lifted out by this extractor: From and by this extra'ctor the cans are delivered into a runway 21 which delivers them to any desired point.
